水 = ㇇ + 亅 + 丿 + ㇏ : Sheldon Shrimp just climbed the Eiffel Tower. He's really thirsty, so he's glad to find a water fountain. After he quenches his thirst, he also finds a snack: A banana is swimming in the water.

土 = 十 + 一 : Tommy Turtle (tu) wants to fix a cross (十) on a flute (一) in the space station's living room (Ø3). He uses dust and clay (土) to hold them together.

In the aorta (ao3), the fool (呆) and Rosa Luxemburg (亻) unite their forces to protect (保) the world and try to lock Beelzebub (b) in a safe (保).

持 = 寺 + 扌 : Charlie Chaplin brought his Buddhist shrine to the space station, but just inside the entrance he realizes that he didn't think of zero gravity as his shrine is about to float away. His only option at the moment is to grasp the shrine with two toy claws and manage it this way.
